Many models will also have the ability to access video from select portable media devices such as Walkman and iPod players via optional Digital Media Port (DMP) accessories, as well as access to digital photos and music via USB devices.

Additionally, XBR6 and Z-series models will be compliant with Digital Living Network Alliance (DLNA) networking systems.

Sony said its product strategy this year is to provide products that allow users to access different types of content not only through the Bravia Internet Video Link module introduced last year, but through the new DMP, USB feature and DLNA networks.

Another new feature in many sets is what Sony calls DMeX, which will allow current and future Sony Bravia TV users to integrate a module for the Internet Video Link, and to add additional modules down the line. All the modules will integrate into an XMB graphic user guide, enabling upgradeability as new technologies evolve, the company said.

In addition, Sony will introduce what is expected to be the first OLED TV set for the U.S. market.

Model XEL-1 (available this month at a $2,500 suggested retail) is an 11-inch OLED TV with a panel depth of just 3 mm (0.11 inches). The display is said to produce a contrast ratio of 1,000,000:1, supporting very deep black levels and a new level of color presentation and picture detail.

In addition to affording very thin panels, OLED technology is said to allow extremely bright pictures with low power consumption, a rapid panel-response time for blur-free motion images and extremely wide viewing angles.

Currently, OLED will only afford relatively small screen sizes, but the technology is expected to evolve rapidly. One of the difficulties in developing OLED for TV was said to be limited longevity under high temperatures, but Sony executives said that panel life for the XEL-1 is comparable to LCDs.

Among the Bravia LCD TVs Sony is introducing are a 32- and 37-inch models in the high-end XBR 6 series. The KDL-32XBR6 and KDL-37XBR6 will ship this summer at prices to be announced. Both feature 1080p resolution, 120Hz MotionFlow high frame-rate technology, DLNA compliance, DMP connection, 24p input compatibility, a 3D graphic user interface, DMeX ready, and four HDMI inputs, two component video inputs and a PC input.
